If you ask most people how a catalytic converter works, they’ll say, “Dirty exhaust from your car’s engine goes in one side and cleaner exhaust goes out the other side. The exhaust gases then go through the muffler and leave the car via the exhaust pipe. That’s pretty accurate, but it lacks some of the subtler information about what really happens in your car’s catalytic converter. It also doesn’t explain what the recyclable precious metals that catalytic converters contain are, or where you can find them. Well, there's nothing like a video...

It took a long time, but this month VW and the U.S. Environmental Protection Agency reached an agreement to compensate owners of VW 2.0 diesels or to repair or buy back their affected cars. So, what does the new agreement mean for you if you collect and recycle catalytic converters for a profit? Although full details of the agreement have not yet been announced, here are some issues to keep in mind if you are hoping that the agreement could yield a windfall in available converters.

What’s the risk of poisoning yourself if you’re storing items made from precious metals that you’d like to recycle? What could happen to you if melt them down and attempt to process them? Actually, chances are pretty good that you’re going to do yourself a lot of harm. Why? Here’s some information you should know.

We just went to the famous New York Auto show and went sniffing for catalytic converters in some of the newest models there. We discovered quite a few new cars that use – or do not use – catalytic converters in interesting ways. 

How much gold, silver, platinum and other precious metals were in those buildings before they burned? Are those valuable metals ever recovered, or are they still waiting to be found in the ashes and rubble? 

We’ve published posts in the past about why recycling gold is socially responsible. Recycled gold doesn’t have to be mined, and mining pollutes air and water and burns fossil fuels. And then there’s the fact that recycled gold is not dug from the earth by underpaid, exploited workers. Of course, it is possible that the gold that we recycle from computer motherboards, old jewelry and other sources does have a “dirty” past – because gold doesn’t have DNA, it is impossible to know whether it originally came from a mine in Africa or from ancient amulets that were stolen from the Aztecs. But even if that is the case, the gold that we recycle today is generations removed from any dirty sources and less closely linked to environmental or societal ills. 

Last year we published a list of the most popular blog posts that we ran in 2014 – the ones that had been viewed by the most people and that had generated the greatest number of comments. We’ve created a different list of best posts this year. They are posts that contain the kind of useful information that can quickly put a lot of money in your pocket – maybe even in time for the holidays. 

We’ve written before on this blog about how to make money recycling gold class rings. Today, let’s take a look at how you can profitably recycle older class rings that contain palladium and platinum. 

We don’t have a crystal ball that lets us see what precious metals you now own – either in bullion, in materials that you haven’t yet recycled or elsewhere - but we’re willing to guess that most of your metals investments fall into the mid-term category that FINRA defines: you’re going to have them for between three and 10 years, so they should be investments that offer stable long-term growth.

It’s overwhelming. How are you going to figure out what you have and what it is worth? How will you know when the right time comes to sell it? Should you wait until prices hit the right levels, and how will you know when that happens? And while you’re trying to answer those questions, you do nothing.

If you’re interested in collecting and recycling catalytic converters for a profit, the arrival of all these high-tech vehicles can get confusing. Which of them contain cat converters, and which don’t?

In the larger restaurants where so many of us eat today – the chains that have the same restaurants that we see whether we are driving near Atlanta, Los Angeles or Boston – most of the food is prepared in an entirely new way.  Partially or completely prepared frozen entrees arrive from central production facilities that resemble factories, not kitchens.  And when those meals arrive, they are stored in freezers and then prepared quickly, using high-tech restaurant equipment.

This could be the best time ever to start a business collecting catalytic converters and sending them to Specialty Metals Smelters and Refiners to be recycled. One thing for certain is that someone will be cashing in on the platinum, palladium, rhodium, cerium, manganese, and nickel that all those scrapped converters contain. If you are motivated to get a piece of the action, that someone could be you. Would starting a company to collect and recycle catalytic converters be a good career choice for you? Here are some steps that can help you decide.

So, what are palladium salts? They are compounds of palladium and other chemicals that are most often used in the production and testing of stainless and other steels. Some palladium salts are also used as catalysts in the production of other chemicals. Here are some common forms of palladium salts that are used in industry, and that you might come to own if you acquire a chemical business or an old industrial site . . .

Chances are that you only find small quantities of the valuable secondary platinum group metals (palladium, rhodium, ruthenium, iridium, and osmium) hiding in recyclable items that you think are made only of platinum. How can you tell if these rarer metals are present?

Recycling precious metals like gold, silver, platinum, palladium and rhodium can be a complicated business. There could be treasure hiding in the most unusual places, and businesses and consumers alike are always on the lookout for tips, tricks and advice. Our top blog posts, as determined by our readers, represent a collection of knowledge you may find just as worthwhile to read as they have.
